Question

Help me with finding the MAD for math please!!!!

Answer 1

The average (mean) absolute deviation of a data set is the average of the absolute deviations from a central point.

so we need to calculate the mean of this data set firstly:::
the mean of (7,10,19,14,3) =
`(7+10+19+14+3)/(5) =10.6`

then we will calculate how far each record is from this mean:::
7-10.6 = - 3.6
10-10.6 = - 0.6
19-10.6 = 8.4
14-10.6 = 3.4
3-10.6 = - 7.6


BUT as it requires the ABSOLUTE mean deviation, we will take the absolute values of the previous results

3.6 & 0.6 & 8.4 & 3.4 & 7.6

Adding them together and divide by the records number (5)::

ABSOLUTE mean deviation =
`(3.6+0.6+8.4+3.4+7.6)/(5) =4.72`


Done!!!

I hope you got the idea
